SPINDLE LOCK.

Application filed December 31, 1921. Serial No. 526,166.

chines, and the primary object of the in vention is to provide a novel retainer or look for preventing the accidental displacement of the spindle from the bolster or support when the bobbin is being removed therefrom. i i

Another objector the invention is to provide a novel retainer or lock which can be readily and quickly associated with a spindle of any approved type, and which will permit the spindle to be easily removed when desired and which is not liable to become broken by rough usage.

A further object of the invention is to other'parts of the spinning machine, and

which is held in place by ordinary parts of the spinning machine and which will tend to reduce vibration between the spindle, bolster and the supports or casting for the bolster.

' A still further object of the invention is to provide an improved lock orretainer for spindles of spinning machines of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed uponthe market at a reasonable cost.

WVith these and other objects in View, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification, in which drawings: t

Figure l is an elevation of a spindle and the supporting structure, showing the novel retainer or lock associated therewith.

Figure 2 is a plan view of a spindle and its supporting structure showing the improved retainer or lock associated therewith.

Figure 3 is a planview of a novel lock or retainer showing the same applied to a spindle and supporting structure, the spindle being shown in cross section.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates a spindle, which is associated or journalled in the bolster B in the ordinarymanner.

The bolster B normally rests upon the supporting bracket C, which is provided with a central aperture (not shown) for the reception of the depending stud D- formed on the bolster. The lower end of the stud D adjustably carries the nut E and between the upper face of the nut and the under side of the support G is confined a spring F, which normally tends to draw the bolster B down into engagement with the supporting bracket (J. l

The supporting bracket C'is provided with an upwardly extendin pin Gr, which normally fits'in a'notch H tormed in the bolster;

The spindle A has mounted upon the same in the usual manner a pulley I, the lower end of which is provided with an outstanding fiange K.

The above described parts are of the ordinary construction and the improved lock L is adapted to be associated therewith without making any change in the formation thereof for retaining the spindle A against displacement. i The improved retainer or look L includes a disc shaped plate 5, which is provided with an axial opening 6, for the reception of the spindle A. This plate 5 is positioned between the-supporting bracket C and the bolster B and if desired, felt washers 7 may be placed upon the opposite sides of the plate and in engagementwith the bracket structure C and the bolster B. These washers will tend to reduce vibration. An upstanding arm 8'is formed on the periphery of the disc 5 and this arm canhave its upperend provided with, a right angularly disposed radially extending leg 10. The leg 10 may in turn terminate in a depending lug 11, which is disposed in parallelism to the arm'8." I

The plate 5, the arm 8, the leg 10 and the car 11, can all be stamped from a single piece of sheet metal of the desired gauge if so desired, and the arm 8, the leg 10 and the ear 11 then bent to the desired shape, as

shown in the drawing. Of course, this is purely optional and the device can be cast if so desired. The arm 8 and the ear 11 are provided with registering openings for slidably receiving a looking or retaining bolt 12. This bolt 12 has coiled around the same an expansion spring 13, which normally engages the inner face of the ear 11 and against a collar 14, which may be secured-directly to the bolt. This spring normally urges the bolt 12 inthe path of the collar K formed upon the pulley I and thus effectively prevents accidental displacement of the spindle A fromthe bolster B. In order to limit the inward movement of the bolt 12 under the influence of the spring 13 and to permit the ready operation of the bolt when itis desired to remove abobbin for any reason, the outer end of the bolt 12 is provided with a pull ring 15. This ring 15 normally engagesthe ear 11 and it is apparent that this ring may be1readily engaged by the finger of the operator of the spinning machine for pulling the bolt 12 rearwardly against the tension of the spring 13. In order to prevent accidental rotation of the plate 5 on the spindle and in order to hold the locking device in anypreferred adjusted position on the spindle so that the same'can beheld out of the way of other parts of the machine, the periphery of the disc 5 is provided at spaced points with looking notches 16, any one of which is adapted-to receive the pin G formed upon the supporting bracket C. In applyin the disc 5 to the spindle, the pin G is p aced in thedesired notch 16 and thus it can be seen that movementof the .discaround the spindle will be prevented.

Now, when a bobbin is being removed from the spindle A, all likelihood of the spindle being displaced from the bolster is precluded by the bolt '12 engaging in'the collar or flange K, and when it is desired to remove the spindle for any reason, it is merely necessary to pull the bolt 12 outwardly, out of thepa-th of the collar.

From the foregoing description, it can be seen that an exceptionally simple and durable lock or retainer has been provided for the spindles of spinningmachines, and which is of an inexpensive character, and which can be readily applied to the ordinary type of spindles now on the market.

Changes in details may be made without departing'from the spirit orscope of this invention; but,

1 claim:

1. The combination of a spindle, a bolster upon which the said spindle is journalled, a supporting member for said spindle, and a retaining device for said spindle including a frame held in place between said bolster and supporting member, and a bolt slidably carried by said frame for engaging the spindle to prevent displacement thereof.

2. The combination of a spindle, a bolster upon 'whichsaid spindle is journalled, a

supporting member for said bolster, a retaming and locking'device for the spindle including a supporting frame secured bespindle, and a handle formed on said bolt I for permitting the convenient operation thereof.

3. The combination of a spindle, a bolster upon which said spindle is journalled, asupporting member for said bolster, a retaining and locking device for holding the spindle in position including a frame confined between the bolster and the supporting member, means for holding the frame in an adjusted position on said spindle, said frame including a supporting disc and an arm, and a sliding bolt carried by the arm for movement toward and away from said spindle.
